Following their engagement, Navid and Adrianna celebrate their respective bachelor and bachelorette parties. While Adrianna feasts with Annie, Naomi, Silver, and their female friends at the Wilson home, Liam takes Navid, Ethan, and Dixon to have a wild night on the town with some college girls at a burlesque club. Meanwhile, sparks fly between Ryan and Jen, and Dixon continues to feel unappreciated by Silver. Jen also persuades Naomi to stand up to their father as well as move in with her at a local house, while Naomi continues to grow more insecure as well as jealous over Liam when she sees him talking with Annie whom he sees as naive and holding back her own dark side.

Naomi and Adrianna take a road trip along the California coast to get away from their respective life problems, but more complications set in when their money and clothes get stolen from Naomi's car, including her wedding ring which prompts them to venture to a seedy biker bar to find their culprits, where Adrianna hooks up with a young motorcyclist and Naomi ventures to visit her estranged mother. Meanwhile, Liam finds himself held captive by the deranged Ashley in the basement of Offshore who has plans to take him to Mexico, while Annie and Vanessa learn that Ashley is not who she says she is. Dixon prepares a party at Naomi's house to celebrate the opening of his new recording label. Megan tells Dixon that she feels that he is not over Adrianna, so in order to move on, Dixon decides to let go of his anger and not feel anything for Adrianna. Elsewhere, Silver is still having problems with Teddy about the impregnation when he continues to want to be a part of her baby's life, while she wants to raise her child alone. Silver goes to Teddy's uncle to persuade him to drop his attempts to block her procedure, but when Teddy still will not back down, a row occurs which makes things worse for everyone.
